But according to the Wall Street Journal(18 August 2012), in the future, it could be encoded in the genetic molecules of DNA.

DNA has “vastly more capacity for their size then today’s computer chips and drives”–where a thumb size amount could store the entire Internet–or “1.5 milligrams, about half the weight of a house ant could hold 1 petabyte of data, which equals to 1,000 1-terabyte hard drives.”

As opposed to binary code, DNA will store information as strands made up of four base chemicals: adenine (A), guanine (G), cytosine (C) and thymine (T).

Just like letters in the alphabet make up words, sequencing of these 4 base chemicals can store biological instructions (e.g. 3 billion for a person) or any other information.

Using DNA for storage involves 4 key steps:

1) Encoding information into binary code

2) Synthesizing the chemical molecules

3) Sequencing them in a string to hold the information

4) Decoding the molecules back into information

Overall, DNA is seen as a “stable, long-term archive for ordinary information”–such as books, files, records, photos, and more.

Researchers have actually been able to store an entire book of genetic engineering–with 53,426 words–into actual DNA, and “if you wanted to have your library encoded in DNA, you could probably do that now.”

With the cost declining for synthesizing and sequencing DNA, this type of data storage may become commercially practical in the future.

And with the amount of information roughly doubling every 2 years, large amounts of reliable and cost-effective memory remains an important foundation for the future of computing.

Frankly, when we talk about storing so much information in these minute areas, it is completely mind-boggling–really no different than the corollary of imaging all the stars in vastness of sky.

It is almost incredible to me that we have people that can not only understand these things, but make them work for us.

With NASA’s Curiosity Rover exploring Mars over 34 million miles away, and geneticists storing libraries of information in test tubes of DNA coding, we are truly expanding our knowledge at the edges of the great and small in our Universe.

How far can we continue to go before we discover the limitations to our quest or the underlying mysteries of life itself?

What is also curious to me is how on one hand, we are advancing our scientific and technological knowledge as a society, yet on the other, as individuals, we seem to be losing our knowledge for even basic human survival.

How many people these days, are proficient on the computer in an office setting, but couldn’t survive in the wilderness for even a few days.

Our skills sets are changing drastically–this is the age of the microwave, but knowing how to cook is a lost art to many.

So are we really getting smarter or just engaging our minds in a new direction–I hope we have the DNA to do more than just one! 😉

Remember the saying, “good things come in small packages?” In enterprise architecture big is out and small is in.This applies not only to the obvious consumer electronics market, where PDAs, phones, chips, and everything electronic seems to be getting smaller and sleeker, but also to the broader computing market (such as the transition from mainframe to distributed computing) and even to the storage device market.

The Wall Street Journal, 10 January 2008, reports that Mr. Moshe Yanai “was responsible for one of IBM’s defeats in the 1990’s, “when he designed the computer storage disks for EMC Corp. that displaced IBM’s in the data centers around the globe.”

How did Mr. Yanai do this?

He did this by going small. “One point of the architecture is simplicity of management of data…with his architecture, you just add more pieces.”

In creating Symmetrix disk drives, Mr. Yanai developed storage drives that were “cheaper, faster, and more reliable than IBM drives…he pioneered a technology called RIAD-short for redundant arrays of inexpensive disks—that linked dozens of the kinds if disk drives used in PCs together to cheaply provide the same storage capacity as refrigerator-sized drives from IBM. Raid technology has since become a standard throughout the storage industry.”

The small disk drives of EMC beat out the big drives from IBM, jus like the PCs (of Dell and HP) beat out the mid-range and mainframes computers of IBM.

Mr. Yanai, a one time Israeli tank commander, is a User-centric enterprise architect.He recognized the needs of his users for smaller, cheaper, and faster devices and he delivered on this. Moreover, Mr. Yanai put the customer first not only in terms of product design and development, but also in terms of customer service. “Mr. Yanai was known as an expert engineer who also could talk to customers and solve their problems. Mr. Yanai put telephones in each storage device and programmed them to ‘phone home’ when it sensed a part was in danger of failing.”

While Mr. Yanai was removed from his top engineering role at EMC, his company XIV corp. has been bought out by IBM and “locked up” his services. IBM may be a little slow (due to its size—a lumbering giant), but they are not poor or stupid and they can buy the competition.Anyone remember Lotus Corp?

From a User-centric EA perspective, the small and agile often wins out over the large and stodgy.It is a lesson thousands of years old, like the biblical tale of David vs. Goliath, when little David defeats the monstrous Goliath. Small is nimble and big is cumbersome. This is the same thing the U.S. military has found out and is converting to smaller, more agile, and mobile forces. EA needs to do the same in focusing on smaller, faster, cheaper computing devices and on simpler, more streamlined processes. Small is truly bigger than big!
